I have tuned my 1st pull truck and went to the pulls to watch my truck run--
It is a 2007 LMM and runs in the "modified street " class at 8000 lbs
Afterwards I spoke to many of the other drivers and it seems ALL of them rev the engine up to 4800 RPM--Ours would only top out at 3800-4000 RPM
These are all race only dedicated pull trucks and no need to criticize the engine danger this does
How or what do I need to do in the tune to get the engine to rev up to 4800 initially from the start of the pull ?
I made all the adjustments in the TCM and ECM I thought would do it but they did not work
The drivers all run in MANUAL mode and do NOT shift--They run in 3rd gear in 4WD drive low---
I am using EFILIVE-- Thanks
